Abstract: An apparatus for dispensing a treatment liquid to a respective agricultural crop, including means for diffusing the treatment liquid, which comprise means for emitting a flow of air for diffusion of the treatment liquid, in particular fan-style diffusion, and means for dispensing the treatment liquid inside the flow of air for diffusing the treatment liquid, connected with means, in particular a respective tank for containing the treatment liquid; the dispensing means including a dispensing body having an inner chamber for conveying the liquid, respective inlet opening means of the treatment liquid, and nozzle means for escape of the liquid in the flow of air for diffusion of the treatment liquid, in communication with or opening into the inner conveying chamber; the inlet into the conveying chamber being defined by a plurality of openings leading into the inner chamber for conveying the liquid.

Abstract: A mixing cartridge for single-lever mixing faucets, which comprises a substantially cylindrical container accommodating a base disk, arranged proximate to one of the end faces of the container and moving two intake ports connectable respectively to a cold and hot water feed ducts, a mixing disk, superimposed on the base disk and crossed by a mixing port. The mixing disk is movable with respect to the base disk, by way of an actuation connected to the mixing disk varying its position and that of the mixing port with respect to the intake ports to vary the degree of opening or the ratio between the degrees of opening of the intake ports. The mixing port is connected to a discharge duct that exits from the container at the end face of the container that lies opposite the base disk.
